Direct Current Vector Optimal Control for Permanent Magnet Direct-Driven Wind Turbines
摘要
Abstract
Direct-driven permanent magnet synchronous generator wind power system with traditional vector control strategy has serval advantages,such as simple algorithm,and reliable implementation.However,there are also slow dynamic response and control link coupling problem.Aiming at it,a direct current vector optimal control for direct-driven permanent magnet synchronous generator wind power system was proposed.The new control strategy was based on traditional dq vector control method.In order to achieve the maximum power point tracking and reactive power control and grid voltage support,the traditional vector control structure was slightly modified,and the nonlinear constraint was introduced with the optimal control theory,and then the new controller was applied to both the generator side and grid side of the wind power converter.In order to verify the validity of the proposed method,the simulation model of the wind power system was built with MATLAB/Simulink platform,and the traditional vector controller and the new controller was simulated and compared.The results showed that,using new type of direct current vector optimal control,the control performance was significantly superior to the traditional vector control.关键词
